Added visual updates and changed some mechanics

After you shoot there will be a fire particle at your gun and a smoke effect, also screen will shake

When you get hurt or you hurt someone, there is a number appears and shows how much you damaged or  got damaged. And if you shoot again before that number disappears, it adds the new damage to old damage.    etc: you hit someone 15 dmg *number appears* you again hit 15 dmg *number changes to 30* and then disappear if no one hits him again.

And again if you got hurt or you hurt someone blood particles will appear and your chracter's color will change to red for a second then turns back to normal.

I added shield but its broke because i realized now when writing this i forgot to put to code to the game. BUT imma release a new version soon (an ui update and bug fixes and also new mechanics,  i will put the shield code in that update)

Extra:

 Changed the map and added particles for map.

Quick note: By the end of this month ill probbably change a few things for gameplay itself (code) and add new mechanics and make the ui more proper and more detailed settings menu
